lz4 1.8.3 was released with a fix for data corruption during compression. While the release notes indicate we aren't vulnerable, be cautious and update anyway. Message-Id: <20181230144716.7238-1-avi@scylladb.com>
Official toolchain for ScyllaDB
While we aim to build out-of-the-box on recent distributions, this isn't always possible and not everyone runs a recent distribution. For this reason a version-controlled toolchain is provided as a docker image.
Obtaining the current toolchain
The toolchain is stored in a file called tools/toolchain/image. To access
the toolchain, pull that image:
docker pull $(<tools/toolchain/image)
A helper script dbuild allows you to run command in that toolchain with
the working directory mounted:
./tools/toolchain/dbuild ./configure.py
./tools/toolchain/dbuild ninja
Building the toolchain
Run the command
docker build -f tools/toolchain/Dockerfile .
and use the resulting image.
Publishing an image
If you're a maintainer, you can tag the image and push it
using docker push. Tags follow the format
scylladb/scylla-toolchain:fedora-29-[branch-3.0-]20181128. After the
image is pushed, update tools/toolchain/image so new
builds can use it automatically.
For master toolchains, the branch designation is omitted. In a branch, if there is a need to update a toolchain, the branch designation is added to the tag to avoid ambiguity.
